Spiders have thus evolved a range of predatory behaviours that, at the same time, allow them to evade the threat of predation – and some of the most effective strategies involve deceiving ants.
The 2014 Nobel Prize for Physiology and Medicine was awarded to three neuroscientists for their pioneering work on the brain’s “inner GPS system”. Over the course of four decades, they revealed that a small part in the brain called the hippocampus stores a map of animals’ surroundings and helps them navigate.
Metamorphosis has fascinated biologists for years. A butterfly may look drastically different from its former worm-like caterpillar self, but we now know that its appearance and memories are tremendously influenced by caterpillar experiences.
Brain computer interfaces have sparked tremendous interest in the field of neuroscience: we are at a stage where monkeys can control robots and people can answer emails simply with their thoughts. But revolutionary systems like these are criticised for their seeming lack of ethical consideration. Are these criticisms entirely justified?
The next revolutionary gaming app? Maybe someday. But to the emerald wasp, this grisly battle is a routine part of its everyday life.
